TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 336,975, dated March 2,1886.

Application filed December 8, 1885. Serial No. l85,0l0. (No model.) I

To aZZ whom it may concern.-

Be it known that I, JOHN F. WoLLnNsAK, a citizenof the United States,residing at Ghicago, Illinois, have invented certain new and usefulImprovements in Transom-Lifters, of which the following is aspecification.

The object of my invention is'to make a transoinlifter which can beeasily and readily set or fastened at any desired position, and adaptedto transoms of various heights from the floor; and my invention consistsmore particularly in the features and details of constructionhereinafter described and claimed.

In the drawings, Figure 1 is'a perspective View of my transom-litter inplace. Fig. 2 is a perspective view of the guide. Fig. 3 is a transversesection taken through the slotted guide-piece and the slidinghead-block. -Fig. 4 is an enlarged view of the lower portion oflifting-rod. Fig. 5 is an enlarged view of the bracket or holder, overwhich the lifting rod slides, and by which it is held in any desiredposition. Fig. 6 is an enlarged view of the lifting -arm connecting thebracket on the transom with the sliding-head block, and Fig. 7 is anenlarged view of such bracket.

A represents the lifting-rod; B, the slotted guide-piece attached to thedoor-jamb; O, the lifting-arm; D, the transom'bracket; E, the transom;F, the sliding head-block; G, the holding and fastening bracket; H,notches or catches in the same; I, a coupling in the lifting-rod, and Ja joint or coupling in the liftingarm.

In making my improved transom-lifter I prefer to make the lifting-rod insections, so that it can be coupled or fastened together in anyconvenient manner, and thus make a lifting-rod of the desired length. Bymaking it in sections the various parts of the transomlifter can bereadily and easily shipped or sent to the place of use, and any transomcan be provided with a lifter and holder with ease and convenience, nomatter what its height from the floor. In like manner I also prefer tomake the lifting-arm in sections, so that it can be readily packed forshipment and made of any desired length to suit the particular transomin connection with which it is to be applied. I make the lower portionor section of the lifting-rod oval or elliptical in shape incross-section. Along the narrow edge of the lifting-rod thus produced Imake any desired number of notches at proper intervals into the rod asufficient distance to make the rod round at the notch. Near the lowerend of the lifting-rod I screw or otherwise securely attach to thedoor-frame a bracket or fastening-piece, provided with a hole, which isalso oval or elliptical in shape, or of a shape corresponding to theshape of the lifting-rod in cross-section through the locking projectionor lug, to permit the lifting-rod to fit the same and to be moved up anddown therein. The lower end of the rod is provided with a handle, knob,or other lifting device, by which the rod may be moved up and down andits revoluble portion turned partially around. I preferably provide aslotted bracket or guiding-box, which may be screwed or otherwiseproperly attached to the d00r-frame at the requisite height, for guidingthe upper end of the lifting-rod in itsmovement up and down, thoughother means of guiding the lifting-rod may be employed. This slottedguide is preferably made of some length, and its slot long enough topermit the guiding of the rod through the whole extent of its movementup and down. When a slotted guide is used, a sliding head-block, F, madewith sidewise extensions at its inner end, as shown in Fig. 3, is placedwithin the slotted guide through an enlargement, preferably at thebottom thereof, and the upper end of the lifting-rod is attached to thesame in any convenient manner. The projections on the inner end of thissliding block prevent it from being removed from the guiding piece orbox except at the enlargement in the slot through which it was inserted.The lifting-arm is also attached to this sliding head-block and to thebracket on the transom. The connection between this lifting-arm and thetransombracket is made preferably as shown in Figs. 6 and 7, and admitsof the bracket being attached either at the right or the left hand ofthe transom. In adjusting the extend of the up and down movement of thelifting-arm care should be taken that when the transom is open to itsfullest extent the projections or extensions on the inner end of thesliding head-block are still above the enlargement in IOC "which may bemade revoluble from its connection through a collar or coupling with theupper portion of the lifting-rod to one side or the other whenever oneof the notches is reached. When so turned, it cannot be moved up or downuntil it has been turned back again and the narrow edge of the rod orthe locking projection or lug made to coincide with the correspondingform of the hole in the fastening or looking bracket. In this Way 20 thetransom may be opened to any extent required and securely and readilyfastened in position.

What I claim is- In a transom-lifter, the combination of atransom-bracket, a lifting-arm, a guidingpiece, a lifting-rod, andlocking guide or bracket, the lifting-rod being partially revoluble andof greater diameter in cross-section in one direction than the other,and provided Witha notch or notches, and the locking piece or bracketbeing provided with a hole of greater diameter in one direction than theother, through which the lifting-rod moves up and down, and in which itmay be partially revolved whenever its notch or notches are coincidentwith the edges of the lockingbracket, whereby the transom may be held orlocked at any desired degree of openness, substantially as described.
